> spark shuffle fails with mesos after 2mins
> ------------------------------------------
>
> Key: SPARK-12583
> URL: https://issues.apache.org/jira/browse/SPARK-12583
> Project: Spark
> Issue Type: Bug
> Components: Shuffle
> Affects Versions: 1.6.0
> Reporter: Adrian Bridgett
> Assignee: Bertrand Bossy
> Fix For: 2.0.0
>
>
> See user mailing list "Executor deregistered after 2mins" for more details.
> As of 1.6, the driver registers with each shuffle manager via
> MesosExternalShuffleClient. Once this disconnects, the shuffle manager
> automatically cleans up the data associate with that driver.
> However, the connection is terminated before this happens as it's idle.
> Looking at a packet trace, after 120secs the shuffle manager is sending a FIN
> packet to the driver. The only way to delay this is to increase
> spark.shuffle.io.connectionTimeout=3600s on the shuffle manager.
> I patched the MesosExternalShuffleClient (and ExternalShuffleClient) with
> newbie Scala skills to call the TransportContext call with
> closeIdleConnections "false" and this didn't help (hadn't done the network
> trace first).
